Posteromedial vertical capsulotomy selectively increases the extension gap in posterior stabilized total knee arthroplasty

ConclusionIn PS-type TKA, it is possible to obtain selective expansion of about 2.7  mm of the extension gap by PMVC. Therefore, gap balance can be acquired by soft-tissue treatment while preserving the bone. The PMVC was a useful method for acquiring gap balance and preserving the bone stock.Level of evidenceIV.
